Oh ok I think I get the idea or atleast the direction to approach this problem at. Reading this makes me wonder why i even thought circular motion. And no were not worried about the argon being re-breathed just how many you take in within an hour. So my guess is I would use the instantaneous...
It says to assume that he had a normal breath rate, and nothing about how much air he inhaled with each breath. And I assume that the atmosphere is uniformly dense.
